Rotational Curves of the Milky Way Galaxy and Andromeda Galaxy in Light of Vacuum Polarization around Eicheon [PDF]
Universe, 2023 Eicheon properties are discussed. It is shown that the eicheon surface allows setting a boundary condition for the vacuum polarization and obtaining a solution describing the dark matter tail in the Milky Way Galaxy. That is, the dark matter in the Milky

Wormhole in the Milky Way galaxy with global monopole charge
European Physical Journal C: Particles and Fields, 2022 Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole.

The Mass of the Milky Way [PDF]
The Astrophysical Journal, 1996 We use the Jaffe model as a global mass distribution for the Galaxy and determine the circular velocity $v_c$ and the Jaffe radius $r_j$ using the satellites of the Galaxy, estimates of the local escape velocity of stars, the constraints imposed by the known rotation curve of the disk, and the Local Group timing model. The models include the systematic

Genesis of the Heaviest Elements in the Milky Way Galaxy [PDF]
Science, 2003 We review the origin and evolution of the heavy elements, those with atomic numbers greater than 30, in the early history of the Milky Way. There is a large star-to-star bulk scatter in the concentrations of heavy elements with respect to the lighter ...

Modelling the Milky Way as a dry Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We construct a model for the Milky Way Galaxy composed of a stellar disc and bulge embedded in a dark-matter halo. All components are modelled as $N$-body systems with up to 8 billion equal-mass particles and integrated up to an age of 10\,Gyr. We find that net angular-momentum of the dark-matter halo with a spin parameter of $ =0.06$ is required to ...

The star-formation history of the Milky Way Galaxy [PDF]
Proceedings of IAU Symposium 258, (2009), 'The Ages of Stars', eds
Mamajek, Soderblom & Wyse p. 11-22, 2009 The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk galaxy evolution.

On the spiral structure of the Milky Way Galaxy [PDF]
Astronomy Reports, 2011 We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e. the assumption that spiral arms are translated into each other for a rotation around the galactic center by 180

The Milky Way and other spiral galaxies [PDF]
EPJ Web of Conferences, 2012 Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation.

Chemodynamical simulations of the Milky Way Galaxy [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractWe simulate the chemodynamical evolution of the Milky Way Galaxy, including the nucleosynthesis yields of hypernovae and a new progenitor model for Type Ia Supernovae (SNe Ia). In our nucleosynthesis yields of core-collapse supernovae, we use light curve and spectral fitting to individual supernovae to estimate the mass of the progenitor, the ...
